TO ALL WHOM IT MAY CONCERN Be it known that I, C. A. WILLARD, of Belleview, in the county of Huron, and State of Ohio, have invented certain new and useful Improvements in Carriage-Shaft Couplings; and I do hereby declare that the following is a full and complete description of the same, reference being had to the accompanying,drawings, making a part of this specification, in which i v Figure l is a side view of the coupling.

Figure 2 is a top view.

Figure 3', a detached section.

Like letters of reference refer to like parts in the views.

In fig. 1, A is the section of the coupling by which it is attached to the axle-tree. B B are a pair of slotted stays, in which slots is journalled a short shaft, C, fig. 2, from which projects the reach-iron D, to which the thills are connected. Each end of this shaft is provided with a flange or collar, E, in the periphery of which is cut a notch, F, thepurpos'e of which will hereafter be shown. On the inner sides of the stays referred to is cut a deep, square groove, in which is fitted the slide or key Gr, fig. 3, and when in lace is shown in fig. in which it will be seen that the lugs H of the slide fit in the slots of the stays, and that their lower ends are rounded out so as to close on the journal ofthe shaft, making by this means a journal cap for the boxes in which the shaft referred to works. It will be obvious that the slide, whcn in the position shown in fig. 1, will secure the shaft from being lifted up outof the stays, at'the same time will allow it to turn freely in the sameas the thills may be lifted from the ground; also, in consequence of the lugs of the slide being between the collars or flanges E, it cannot slip out from the groove unless the thills are turned up to the position indicated by the dotted line a, fig. 1, in which case the notch F will be brought in range with the slide, which may then be drawn out and the shaft removed from the slot.

' What I claim as my improvement, and desire to secure by Letters Patent, is

The slide G, as arranged, in combination with the stay B and shaft C, provided with a notch, F, for the purpose and in the manner as set forth.
